Re: MPLS TE with EIGRP is now possible

i guess then it is not " contrain based " , since next hop's are explicitly
mentioned .

Regardless of current status of links , TE tunnel always steers the path
dictated by you, even though there are other paths with sufficient
bandwidth . those are kept idle .

since eigrp is not link state , the choice of TE IGP is ospf/isis.

you cant get true TE tunnels contending for resources , based on " current
" availability of bandwidth ...with eigrp ....

i would not be surprised if RIP becomes TE IGP , in which TE explicit
 tunnels are like " static GRE " tunnels
